SPECIFICATION forming part of Letters Patent No. 383,96,dated .Tune5,1888.

Application filed December 20,1887. Serial No. 258,457. (No model.)

To all whomit' may concern:

Be it known that I, HENRY Q. MAURINO, of Albuquerque, in the county ofBernalillo and Territory of New Mexico, have invented a new and ImprovedWheel, of which the following is a full, clear, and exact description.

The object of the present invention is to improve the construction ofwheels, securing thereby cheapness, lightness, durability, and .1oincreased efficiency, and the invention consists in the construction andcombination of the various parts, all substantially as hereinafter morefully described, and set forth in the claims.

Reference is to be had to the accompanying I5 drawings, forming a partof this specification, in which similar letters of reference indicatecorresponding parts in all the gures.

Figure 1 is a side elevation of the wheel. Fig. 2 is an enlargeddiametrieal section taken 2c at the vhub port-ion of the wheel. Fig. 8is a vertical section on line y y of Fig. 2, and Fig. 4 is a perspectiveview of one of the spokes employed in the construction ofthe wheel.

In the construction of the present wheel 1 employ a peculiar-shaped hub,A, and a peculiarly-formed spoke, B. The hub consists of a block orcasting, C, of polygonal or.circu lar shape in crosssection, partakinglongitudinally more or less of the form of duplicate frustums of apyramid or cone, but preferably having its converging sides more or lesscou caved. This hub-block C, at suitable inter vals ofits periphery andat each side, is pro vided with grooves or slots ce of suitable depthfor the inner biiurcated ends, b, of the spoke B. y

The hub-block C is provided with an interior chamber having concavepolygonal walls d, within which chamber, at the ends of the hub,head-blocks E are inserted, having their peripheries made to conform tothe contour of the aforesaid chamber-walls, whereby the blocks aresnugly held in the hub and prevented from turning.

A plate, f, is secured to the blocks E in any suitable manner, the saidplates being adapted to project outward liush, or nearly so, with thereduced ends of the hub, constituting, substantially, a cap therefor.The cap may be of integral portion ofthe blocks, if found desirable,

without departing from the spirit of the invention.

Thehead-blocks and cap-plates are provided with a central bore, g, forthe reception of the aXle-boX F, and headed and screw-threaded bolts 7Lare passed longitudinally through the easing, the head-blocks, and caps,each bolt being provided with a screwnut at its threaded end. By meansofthe aforesaid bolts the hub is purposcd to be tightened. The caps fare 6o respectively rabbeted or recessed, as at k k2, for the receptionof the axle-shoulder m and securing-nut Z.

W hen the spokes lB are inserted, their bifurcated ends b span theperiphery ofthe casting or body ofthe hub and lie within the respectiverecesses d, the extremities of the members being in contact with theeap-platesf, as best shown in Fig. 2.

The inner surface of the felly N is polygonal 7o in contour, the anglesn therein corresponding in number to the number of spokes designed foruse in the construction of the wheel, the periphery of the said fellybeing circular and provided with the usual tire, secured thereon in anyapproved manner.

In the further construction ofthe wheel the outer end of the spokes,which are usually beveled from the center in opposite directions, aremade to lie within the angles n ofthe felly, as 8o illustrated inFig. 1. It will be readily observed t-hat by turning or screwing up thebolts lL the cap plates f will be drawn toward the center of the hub,effeetually tying the inner ends of the spokes in their recesses, and atthe same 8 5 time lengthening the spokes to such a degree as that theywill be forced to a irm contact with the i'elly at their outer ends.

In small and light wheels the outer ends of the spokes are provided witha metallic bush- 9o ing-block, p, into a socket of which the tenoned endof the spoke is entered, as illustrated in Fig. 4, the purpose of thebushing being to afford greater bearingsurfaee at the outer end of thespokes, and also to strengthen the felly.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a hub having opposing and spaced periph eralrecesses, ofspokes reo I provided with bifurcated inner ends vtillin gsaid recesses, a felly engaging the outer ends of the spokes, oap-platesclamping the bifurcated ex tremities of the spokes, and means7substantially as described, for drawing the cap-plates toward the centerofthe hub, whereby the spokes are clamped to the hub and felly, as setforth.

2. The combination, with a hub having op posing and spaced peripheralrecesses, ofspokes provided With biturcated inner ends lling saidrecesses and angular outer ends, a fell y having a polygonal inner face,the angles whereof correspond to the number ofspokcs and their anguiarouter ends, capplates engaging the bi,- fureated extremities of thespokes, and means, substantially as shown and described, for drawing thecap-plates toward the center of the hub and compressing the bifnrcatedends of the spokes, as set lforth.

8. The combination, with a hub provided With a series of opposing andspaced peripheral recesses, and an interior chamber having polygonalWalls, and head-blocks inserted in said chamber, of a contourcorresponding to the Walls thereof and apertnred to receive theaxle-box, of spokes provided with bii'urcated inner ends iitting saidrecesses and having angular' outer ends, a felly having a polygonalinner face, the angles whereof correspond to the number of spokes, andcap-plates secured to said head-blocks and ,engaging the bifurcatedextremities of the spokes, substantially as shown and described.

et. The combination, with a hub provided With a series of opposing andspaced pcripheral recesses, and an interior chamber having pologonalwalls, and head-bloeks inserted in said chamber, of a contourcorresponding to the Walls thereof and apertured to receive an axle-box,of spokes provided with bifurcated inner ends tting said recesses andhaving angular outer ends, a felly having a polygonal inner face, theangles whereof correspond to the number of spokes, cap-plates to saidheadblocks, engaging the bifurcated extremities of the spoke, and boltspassing through the capplate, headblocks, and hub, provided with asuitable head and nuts, all adapted to operate substantially as and forthe purposes herein set forth.
